Adhesive and packaging laminate using the same

[Abstract] The present invention discloses an adhesive and packaging laminate using the adhesive. The binder contains a polyisocyanate and a partially acid-modified polyol. The partially acid-modified polyol is a product of the reaction of a polyol and a certain proportion of anhydrous trimellitic acid and anhydrous trimellitic acid ester. It is: 10-70% by weight of anhydrous trimellitic acid, 90-30% by weight of anhydrous benzene trimerate, and 100% by weight of anhydrous trimellitic acid and anhydrous trimellitate. . The packaging laminate has first and second sheet-like substrates and the above-described adhesive that laminates the first and second sheet-type substrate substrates.

[Sovereign Items] 1. An adhesive comprising: a polyisocyanate; and partially acid-modified polyols including polyols reacted with a certain percentage of anhydrous trimellitic acid and anhydrous trimellitate The proportion of the product is: 10-70% by mass of anhydrous trimellitic acid, 90-30% by mass of anhydrous trimellitic acid ester, and the total amount of anhydrous trimellitic acid and anhydrous trimellitic acid anhydride. 100% quality.
